Referring to FIG. 1, a section view of an inhalation device 100 in accordance with an illustrative embodiment is shown. The inhalation device 100 can include a housing 112, a first cartridge 114, a second cartridge 116, a power source 122, a controller 124, a communication device 146, and a light device 126. In other embodiments, one or any number of cartridges can be used.

The housing 112 can be a long cylindrical shape, for example, the shape and size of a cigar, cigarillo, or cigarette. In other embodiments, the inhalation device 100 can be configured as other smoking or vapor delivery articles such as a hookah, a pipe, an inhaler, or a humidifier. The housing 112 can include an outlet hole 128 at a first end (i.e., a mouth end), where a user can place his lips to breathe in vapor or gas generated by inhalation device 100. The housing 112 can include an inlet hole 130 to allow air to enter the housing 112 when a user sucks on the first end. The housing 112 can be made of paper (e.g., paper rolled up in tubular shape), plastic, metal, wood, glass, or any other material.

The first cartridge 114 can be configured to retain and release a first substance such as nicotine. For example, the first cartridge 114 can include a medium such as a cotton fabric or a comparable material rolled up or shaped to fit inside housing 112. The cotton fabric can be soaked with the first substance. The first substance can include any drug, scent, transport agent, coloring, or a combination thereof. In one embodiment, the first substance is configured such that the substance can be vaporized or gasified. The first cartridge 114 can include a first release device 118.

The first release device 118 can include one or a combination of a heating element, a vibration generator such as an ultrasonic or a piezoelectric transducer, an atomizer, or any other actuator to energize particles of the first substance such that the particles are released from the first cartridge 114 into a gas form or microscopic droplets that can be carried off by air stream, for example, an airstream between the inlet hole 130 and outlet hole 128. The first release device 118 can be configured to control or meter the amount or rate of first substance released from the first cartridge 114. In some embodiments, the inhalation device includes a single cartridge.

The second cartridge 116 can be configured to retain and release a second substance such as a scent. For example, the second cartridge 116 can include a medium such as a cotton fabric or a comparable material rolled up or shaped to fit inside housing 112. The cotton fabric can be soaked with the second substance. The second substance can include any drug, scent, transport agent, coloring, or a combination thereof. In one embodiment, the first substance and the second substance are difference substances. In another embodiment, the first substance and the second substance are the same substance. In one embodiment, the second substance is configured such that the substance can be vaporized or gasified. The second cartridge 116 can include a second release device 120. The second release device 120 can be embedded in or placed near the medium of the second cartridge 116. The second release device 120 can include one or a combination of a heating element, a vibration generator such as an ultrasonic or a piezoelectric transducer, an atomizer, or any other actuator to energize particles of the second substance such that the particles are released from the second cartridge 116 into a gas form or microscopic droplets that can be carried off by airstream, for example, an airstream between the inlet hole 130 and outlet hole 128. The second release device 120 can be configured to control or meter the amount or rate of second substance released from the second cartridge 116. The first cartridge 114 and the second cartridge 116 can be arranged such that the airstream passes over and/or through both the first cartridge 114 and the second cartridge 116. In other embodiments, the inhalation device can include multiple cartridges.

The power source 122 can provide power to the first cartridge 114, first release device 118, the second cartridge 116, second release device 120, the controller 124, the communication device 146, and the light device 126. The power source 122 can be a battery such as an alkaline battery, a nickel metal hydride battery, a lithium-ion battery, a rechargeable battery or any other energy source. In other embodiments, the power source 122 can be external to the housing 112.

The light device 126 is configured to simulate the burning on the tip of a cigar or cigarette. The light device 126 can include a light emitting diode (LED), a resistance-type lamp, an organic light emitting diode (OLED), or any other light emitting device. The light device 126 can be configured to vary intensity based on the amount of airflow between the inlet hole 130 and outlet hole 128.

The controller 124 can be configured to control the first release device 118, the second release device 120, the communication device 146, the power source 122, and the light device 126. The controller 124 can be operatively and communicatively coupled to the first release device 118, the second release device 120, the communication device 146, and the light device 126. The controller 124 can be a processor such as a central processing unit, an application specific integrated circuit (ASIC), a state machine or any other controller. The controller 124 can include memory which can be any type of permanent or removable computer memory known to those of skill in the art. The memory of controller 124 can be a computer-readable storage medium. The controller 124 can include software for controlling the first release device 118, the second release device 120, the communication device 146, and the light device 126, which can be implemented as computer-readable instructions configured to be stored on the memory of controller 124.

The communication device 146 can be configured to allow a user to change and monitor the settings and state of the inhalation device 100. For example, in one embodiment, communication device 146 can be used to reprogram a part of the control logic of controller 124 to limit the usage of the inhalation device 100. The communication device 146 can include at least one of a switch, a keypad, a display, an input/output port, and a wireless transceiver. In one embodiment, the input/output port and the wireless transceiver can be employed to create a communications link between the controller 124 and an external computer, such as a cell phone or personal computer.

Referring to FIG. 2, a schematic of an inhalation device control system 200 in accordance with an illustrative embodiment is shown. The inhalation device control system 200 can include a first release device 218 associated with a first cartridge 214, a second release device 220 associated with a second cartridge 216, a power source 222, a controller 224, a timer 248, a counter 242, sensors 240, a communication device 246, and a light device 226. The controller 224 can be operatively and communicatively coupled to the first release device 218, the second release device 220, the power source 222, sensors 240, the communication device 246, and the light device 226. The inhalation device control system 200 can be, for example, discrete, integrated as a chip, or a printed circuit board assembly.

The first cartridge 214 and second cartridge 216 may each contain a unique substance or a mixture of two or more substances and the mixture composition for one cartridge is different from another. For this reason, the first release device 218 and the second release device 220 can each be operated in a unique way to optimize the effect of the substance for the user. Furthermore, different techniques can be employed for releasing the substances of different cartridges.

Sensors 240 can be, for example, a flow sensor, a thermocouple or pressure sensor to detect the air stream passing through the device or a group of sensors to detect any one of or a combination of airflow, temperature change, pressure change, illumination of light, current change, voltage change, and other physical and electrical properties. Sensors 240 can be located within or on a housing associated with the inhalation device control system 200.

The controller 224 can be configured to control and monitor the first release device 218, the second release device 220, sensors 240, the communication device 246, the power source 222, and the light device 226. The controller 224 can be a processor such as a central processing unit, an application specific integrated circuit (ASIC), a state machine or any other controller. The controller 224 can include a memory 280 which can be any type of permanent or removable computer memory known to those of skill in the art. The memory 280 of controller 224 can be a computer-readable storage medium. The controller 224 can include software for controlling the first release device 218, the second release device 220, the communication device 246, and the light device 226, which can be implemented as computer-readable instructions configured to be stored on the memory 280 of controller 224.

The communication device 246 can include at least one of a switch 271, a keypad 273, a display 250, an input/output port 277, and a wireless transceiver 279. The input/output port 277 can be, for example, a serial port. The wireless transceiver 279 can be, for example, a Wi-Fi transceiver compliant with the IEEE 802.11 standard or a Bluetooth transceiver.

In one embodiment, the switch 271 can be a simple manual switch on a housing for sending reprogramming instructions to the controller 224 by clicking the switch 271 (e.g., clicking the switch five times with the clicking speed at one click per second or faster can reprogram the controller 224 to allow five puffs in a given period and then turn the device off). In another embodiment, the switch 271 can be a dial located on or in the middle of the housing for sending reprogramming instructions to the controller 224 such that by turning the dial the user can set the limit amount of the substance to be taken or inhaled. The dial switch can also be a section of the housing itself. In another embodiment, the switch 271 can be a shock or sound sensor such as a microphone for the user to tap for sending reprogramming instructions to the controller 224. The user can give the device taps at certain speed to set a desired amount of the substance to intake or inhale in a given period. In another embodiment, the switch 271 can be a light sensor to detect energy emitted by a laser, infrared, or other visible or invisible light source. Reprogramming instructions to the controller 224 can be on or off signals from the light source.

The user may use communication device 246 to reprogram the limit value in the controller 224. For example, a simple form of communication device 246 can be a manual switch the user can press or turn on or around the housing. By clicking or turning the switch manually, the user can change the limit setting in the controller 224. For example, by clicking the switch four times with a frequency of 1 Hz or higher, the user can smoke one cigarette equivalent worth of substance in each cycle or 10 each time, and clicking the switch two times will give a half cigarette worth of substance in each cycle. If the manual switch is a dial switch on the housing, the dial setting can set the limit. For example, the dial has indicator lines around it on the non-moving portion of the housing, and setting the dial at one can be equivalent to one cigarette dose per cycle and setting it to one half means a half of a cigarette dose.

The display 250 can be located on within or on the housing associated with the inhalation device control system 200. The display 250 can show messages indicating the usage to help the user keep track of his use of the device. The display 250 can be, for example, a light, a series of lights, a segmented display or a pixelated display. The display 250 can be made, for example, of LEDs, a LED panel, a liquid crystal display, a group of small light bulbs, or electronic ink. The display 250 can display indications to the user, for example, as letters, dots, symbols, a series of lines, figures, pictures, shapes or signals. The display 250 can be monotone or multi-colored.

The display 250 can indicate the usage level for the user to monitor the use of the device and can send out messages to encourage the user to cut down on the use based on the progress he or she makes. A display message can include a number of cigarette equivalents used or left on the inhalation device control system 200, a number of puffs (i.e., drags) used or left on the inhalation device control system 200, and it can include a real time display of a number of puffs the user is allowed to take in each cycle as he or she uses the inhalation device control system 200. This way the device alerts the user, as he or she uses it, how many cigarette equivalents he or she is taking in a given period since using the same device for a long time may lead the user to a false sense of the substance usage. For example, the inhalation device control system 200 with a full first cartridge 214 and second cartridge 216 can be equivalent to one pack of cigarettes and the display 250 can clearly indicate the number of cigarette equivalents or puffs left in the first cartridge 214 and second cartridge 216 as he or she uses the inhalation device control system 200.

The timer 248 can be configured to measure an amount of the substance disbursed and/or to meter a predetermined amount of the substance to a user. The timer 248 can be separate from or integrated with controller 224. The timer 248 can be configured to measure, for example, the amount of time elapsed between user puffs, the amount of time the first release device 218 and the second release device 220 are activated, and the time between uses.

The timer 248 can be configured to measure an amount of the substance disbursed and/or to meter a predetermined amount of the substance to a user. The timer 248 can be separate from or integrated with controller 224. The timer 248 can be configured to measure, for example, the amount of time elapsed between user puffs, the amount of time the first release device 218 and the second release device 220 are activated, and the time between uses. The timer 248 can be activated, for example, by an airflow sensor or a pressure switch. The timer 248 can be configured to measure a duration of a puff while the sensors 240 are activated.

The counter 242 can be configured to count a number of puffs taken per given period by a user. The counter 242 can be separate from or integrated with controller 224. The counter 242 can be configured to measure, for example, a number of puffs taken by a user during a smoking session, a day, a week, a month, or any other time period. The counter 242 can be activated, for example, by sensors 240.

For a more precise control of the amount of the substance allowed in a given period, timer 248 can be used to time the airflow through the device. Each time sensors 240 such as a flow sensor or a pressure switch are activated by the airflow, timer 248 can measure the duration of the airflow and the time for duration can be accumulated in a given period to activate a limit feature according to a substance distribution limit set in the control logic. Also counter 242 can be used to count the number of activations of sensors 240.

Counter 242 and timer 248 can provide usage data on the number of puffs per given period and timer 248 can provide both time duration of airflow for each puff and total time accumulated for the airflow over a given period. Therefore, when the substance distribution limit is set by the user or preset by the factory, the limit can be set on the actual amount of the substance in terms of total time allowed for airflow within a given period for use, not just an allowable number of puffs. Since an amount of airflow for a puff is different from person to person, setting a number of puffs as a limit can allow different amount of the targeted substance delivered to each different user or even to a same user depending on duration of each and every puff. Therefore, using timer 248 to monitor the usage along with counter 242 can provide a more accurate estimate of the measurement of the total airflow.

The inhalation device control system 200 can come with a factory setting for the allowable amount of the substance contained in the cartridges (214, 216) to be released. Different users have different usage habits: One person may prefer long hard puffs and another person may like short shallow puffs. A person having long hard puffs usually finishes a cigarette in a less number of puffs than the person having the short shallow puffs. For this reason, the amount of substance allowed can be set as total duration time that is a time accumulation value of the total puffs in a given period. Another sensor such as a current sensor for the releasing means or the power source or a flow sensor with the air speed measurement can be applied to estimate the quantity of the substance use whenever the user draws the air through the device, and this information can be used along with the timer to calculate the more accurate amount of the substance use. Once the limit value as the time accumulation is set, timer 248 measures the duration of each puff and send the data to the control logic in controller 224 and controller 224 accumulates and compares the accumulated data with the set limit value. Once the accumulated time value or the value calculated from a combination with the accumulated time and the data of the quantity of the substance from the sensor reaches or goes over the limit value, controller 224 turns the inhalation device control system 200 off or makes the inhalation device control system 200 go into a low level mode in which the inhalation device control system 200 releases the substance at a lower rate than during the earlier period. The limit value can be set with cycles. For example, once the device is on, the user can be allowed a first set time limit for the total duration time of puffs within five minutes that is roughly equal to smoking one cigarette, and within a given period such as twelve hours or a day, the user can be allowed to use the inhalation device control system 200 a set number of times. Once the limit is reached controller 224 can turn off the releasing means (218, 220) to stop the substance flow to the user until the next cycle begins after non smoking time expires between two consecutive cycles or controls the releasing means (218, 220) such that the substance flow to the user is more limited per puff until the next cycle begins.

Referring to FIG. 3, a schematic of the inhalation device control system 200 of FIG. 2 with additional sensors in accordance with an illustrative embodiment is shown. The inhalation device control system 200 can include a first release device 218 associated with a first cartridge 214, a second release device 220 associated with a second cartridge 216, a power source 222, a controller 224, a timer 248, a counter 242, sensors 240, a communication device 246, and a light device 226. The controller 224 can be operatively and communicatively coupled to the first release device 218, the second release device 220, the power source 222, sensors 240, the communication device 246, and the light device 226. The communication device 246 can include at least one of a switch 271, a keypad 273, a display 250, an input/output port 277, and a wireless transceiver 279. As discussed further below, the inhalation device control system 200 can measure substance usage in ways other than using a flow sensor or a pressure switch.

The first release device 218 and the second release device 220 can release a first substance from the first cartridge 214 and a second substance from the second cartridge 216 using, for example, heat and/or vibration. A temperature sensor 291 located on the second cartridge 216 can be used to detect the temperature of the second cartridge 216. The controller 224 can estimate an amount of substance released by the second cartridge 216 based on temperature information from the temperature sensor 291, along with information from timer 248. A vibration sensor 292 located on the second cartridge 216 can be used to detect the agitation of the second cartridge 216. The controller 224 can estimate an amount of substance released by the second cartridge 216 based on agitation information from the vibration sensor 292, along with information from timer 248. A current sensor 293 located on the power feed to the first release device 218 can be used to determine the current used by the first release device 218. The controller 224 can estimate an amount of substance released by the first cartridge 214 based on current information from the current sensor 293. Alternatively, a voltage sensor can be used.

In another embodiment, a current sensor 294 located on the power feed from power source 222 can be used to estimate the current used by the first release device 218 and second release device 220. The controller 224 can estimate an amount of substance released by the first cartridge 214 and the second cartridge 216 based on current information from the current sensor 294. Alternatively, a voltage sensor can be used. In another embodiment, a light sensor 295 located in proximity to light device 226 can be used to estimate the usage of the first release device 218 and second release device 220. The controller 224 can estimate an amount of substance released by the first cartridge 214 and the second cartridge 216 based on the amount of time the light sensor 295 is activated as well as the intensity detected by the light sensor 295. Alternatively, other sensors can be used as is known in the art. Alternatively, sensors 291-295 can be place in various locations as is known in the art.

An illustrative inhalation device package for the market can be, for example, a smoking device in a cigarette form that comes with a capacity for smoking about twenty cigarettes. A factory setting can be preloaded to the smoking device to allow about fifteen puffs per use within five minutes, and after the user is done smoking for the time, he or she has to wait at least 30 minutes before using the device again. A display on the inhalation device can show the number of cigarette equivalents left to go, and it can also show the user the number of puffs left to go before the current use is expired as he or she use the inhalation device. In such a setting, the inhalation device can be programmed to monitor the usage of the substance contained in a cartridge by measuring the number of intake, or calculating the quantity of consumption of the substance from data collected from timer for the duration of each and every intake of the air and another sensor such as a electric current sensor or air flow sensor for the rate of flow of the substance. The number of puffs can then be translated to actual substance used based on the calculated estimation from the data provided by the timer and the sensor. Also a counter in the system can be used to count the number of intakes to provide the data to the control means to make calculation simpler. The user may use a button or a dial to change the factory settings such as the number of puffs allowed per use (e.g., from fifteen puffs setting to twenty puffs) and the duration of off time after the use before the next use is permitted (e.g., 30 minutes factory setting to 45 minutes or to 15 minutes). There can be one or more buttons or dials on the inhalation device to reprogram the settings for the inhalation device. A first button or dial for setting the off time duration and a second button or dial for setting a number of puffs allowed per use or other settings depending on the user preference and convenience.

One or more flow diagrams may have been used herein. The use of flow diagrams is not meant to be limiting with respect to the order of operations performed. The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
